PROBLEM TO BE SOLVED: To enable selecting of desired load traffic information in the screen with ease. SOLUTION: A map drawing part 13 draws a map image around driver's position on the first video RAM 10, and a VICS information drawing part 14, based on the VICS information received with FM duplicated broad cast, marks K1 and K2 of traffic congestion information on the second video RAM 11. A key assign part 16 assigns a specified area of touch keys TH1 and TH2 to the end of the marks K1 and K2 of congestion information coming into the screen, and registers it in accordance with congestion information. A mark icon drawing part 15 draws icons E1 and E2 in the position corresponding to the touch key of the third video RAM 12. Out of the first-the third video RAMs 10-12, the picture for one display whose center is driver's position is synthesized and outputted into a display devices 5. When a user touches the icon E1 of desired congestion information in a screen 5A, a touch type coordinate input device 6 outputs touch coordinate, and an input analyzing part 17 references to the resistor content of the key assign part 16, so that corresponding congestion information is discriminated. |
